MMP9 Antibody / Matrix metalloproteinase 9, 100ug

Gelatinase B antibody targets Matrix metalloproteinase 9, a secreted zinc-dependent endopeptidase encoded by the human MMP9 gene and a key member of the matrix metalloproteinase family. Matrix metalloproteinase 9, also widely known as MMP9 and MMP-9, is historically referred to as Gelatinase B due to its strong enzymatic activity against gelatin and type IV collagen. The name Gelatinase B originates from early biochemical characterization studies, while MMP9 represents the standardized gene symbol. Gelatinase B antibody and MMP9 antibody therefore refer to detection of the same extracellular protease involved in matrix remodeling and inflammatory signaling.<br><br>MMP9 is synthesized as a latent proenzyme that undergoes proteolytic activation to generate the active catalytic form. It efficiently degrades type IV collagen, gelatin, elastin, and additional basement membrane substrates, facilitating cell migration, angiogenesis, and extracellular matrix reorganization. Gelatinase B activity is tightly regulated by tissue inhibitors of metalloproteinases, particularly TIMP1, to maintain tissue integrity during normal repair processes. Dysregulated MMP9 expression contributes to cancer metastasis, chronic inflammatory diseases, cardiovascular remodeling, and blood-brain barrier permeability.<br><br>Gelatinase B is highly expressed in neutrophils, macrophages, activated endothelial cells, and certain tumor cells, especially under inflammatory stimulation. Elevated MMP-9 levels frequently correlate with increased tumor invasiveness and poor clinical outcome in multiple malignancies. Beyond oncology, MMP9 plays important roles in wound healing, immune cell trafficking, and vascular remodeling.<br><br>Structurally, Matrix metalloproteinase 9 contains a signal peptide, propeptide region, catalytic zinc-binding domain, fibronectin type II repeats that enhance gelatin binding, and a C-terminal hemopexin-like domain that contributes to substrate specificity and protein interactions. A Gelatinase B antibody is suitable for detecting MMP9 expression in extracellular matrix remodeling, inflammatory signaling, and tumor progression research applications.
